==========================

The Dunphy's are a simple suburban family in Los Angeles, not much different from any other family other then the talking to themselves part, Y/n hasn't quite understood why they do that yet, Y/n L/n is the boyfriend to their oldest daughter and child, Haley, they've been dating for a little while now, nothing too crazy but they spend more time in her room then anything else.

Haley: Fuck baby ~

Haley has her arms and legs wrapped around him as he fucked her in missionary, they've been dating since pretty much day one of Highschool, it was only natural that they'd be each other's first's, although this isn't their first, that was a while ago, now they both just can't keep their hands off each other.

Y/n: Oh fuck ~ I love you ~

Haley smiled to him and brought him into a kiss making Y/n kiss back, Haley has already cum once and she just needed to feel his load inside her again, she isn't worried about getting pregnant, sure it will be an issue but she's on birth control so the odds are that they'll be fine, as Y/n continued to fuck his girlfriend, they had no idea that Alex, Haley's younger and more nerdier sister was peaking at them through Haley's bathroom door.

Alex: Nice Alex, real nice.

Alex came down here to see if she can find something she's misplaced, sure the odds are it's not in the basement that Haley calls her room but it's nowhere else she could think of so this is the last place, how was she supposed to know that her sister and boyfriend were going to start fucking as soon as they got down here

Alex: Just ignore them. They'll finish and leave, then you can get out without them knowing you were even here.

Alex crossed her arms as she waited and waited for them to finish, they've already been going a while so surely they won't be going for much longer, also Alex couldn't help but become a little curious from her older sister's moans, she needed to take another peak only this time she watched as Haley was on top, gridding and bouncing on her boyfriends, honestly pretty big cock.

Haley: Come on baby ~ Cum for me ~

Y/n looked like he's focused on her, his hands gliding over her skin, there's never been any doubt that the two love each other, there always so close and clearly they can satisfy the other, Haley was really starting to ride him, her hands pushed on his chest as she bounced her ass up and down on his cock, their faces inches from the others, their saying something but Alex couldn't hear them, she was just starting to enjoy what she was seeing.

Alex: That uh... That's actually pretty hot ~

Alex continued to watch as her sister bounced her hips on his cock, his fight hand gripped to her waist as his left hand held her head into a kiss that looked like neither could breath but they didn't care, clearly they just wanted to fuck like rabbits in heat and that's just what their doing, Alex didn't even realise that she's starting to touch herself, her left hand caressing her own breasts while her right hand rubbed her pussy over her pants.

Alex: Oh God ~ No, I can't. That's so wrong.

Alex went back to crossing her arms as her sister's moans and her boyfriends groans can still be heard clearly to her, it was so wrong that it's turning her on but she can't help it, she's imagined having sex so much in the last few weeks now and to be completely honest, she's been picturing Y/n every single she even had a wet dream the other day about him, he snuck into her room, crawled into her bed and ate her pussy clean, it was the best dream she's ever had.

Alex: Just the once won't be so bad. Right?

She asked herself as she looked back through the crack in the door, Alex put her right hand inside her pants this time to rush the job and enjoyed what she was seeing, Haley getting fucked by her boyfriend, her hot, captain of the football team boyfriend, he's probably the brunt of every girls wet dreams but Haley get's him, he's hers and no one else, Alex isn't all that jealous about many things but that is one of them, what she wouldn't do to be the one riding him right now.

Alex: Oh Y/n ~

Alex was quick to cover her mouth not caring that the hand she's doing it with is the hand that was just rubbing at her pussy, she might have been a little too loud with that one, it wasn't her fault, it just felt so good, all she could hope was that they didn't hear her, the silence coming from the room though was enough to make her think that something was wrong.

Haley: What was that?

Alex couldn't see them anymore because she moved away from the little gap in the door but she can tell that her sister is talking about her moaning her boyfriend's name, she then heard a little bit of shifting but that was just Y/n moving to his elbows looking up to Haley.

Y/n: That wasn't you?

Haley shook her head "No" at him while actually looking pretty scared at the bathroom door, Haley's mind wasn't telling her it was her sister watching them, her mind was telling her that it was one of her followers again, it wouldn't be the first time she's had to deal with a stalker, well, Y/n dealt with him actually but Y/n could tell right now that the moments ruined and Haley is rocked by what she heard.

Y/n: Hold on. I'll check it out.

Haley climbed off him as he moved to get off the bed, Alex tried to think fast but there wasn't really much she could do, the only place to hide for her is in the shower but the first thing he's going to do is draw the curtain when he walks in here, so she just waited while trying to think of an explanation.

Y/n: See, there's nothing...

Y/n was about to tell her it's all clear and nothing is in here but he can't because Alex is right there, she begged him to be quite, Y/n didn't really know what to do or say, neither did Alex because he's right there in front of her, naked and his cock's still hard, Alex tried not to look at it but she couldn't help it, he's much bigger than she expected.

Y/n: ... There's nothing here.

Y/n turned to face Haley who's sitting on the bed watching him, he knew that if Haley found out Alex was in here then things will be a lot more awkward between them, sure their not as at each other as they used to be but this might make them mending their bound a lot harder to do, Alex sighed with heart palpitations as Haley nodded to him, they both said something about the moment being ruined and the mood is gone, all Y/n cared about the is her.

Y/n: Did you cum at least?

Haley nodded to him with a small smile, she came twice and that's all Y/n wanted to know, Haley did ask if he had, she knew he hadn't but Y/n waved it off like it was nothing, he didn't honestly mind and once Alex gets out of here, he can get in the shower and finish himself off, sure he'd rather cum inside Haley but he isn't going to force her if she doesn't want to.

Haley: Sorry baby. I'm gonna get something to eat. You want anything?

Y/n shook his head "No" to her with a smile, it's not so bad to have a moment ruined and it doesn't affect him like it would others in the world, he did though get curious to why Alex was here in the first place, so he turned back to her, his naked body still not covered up, he's not trying to do anything but he's just not that awkward in his birthday suit.

Y/n: You really need to explain. I just lied for you and got blue balled, so this better be good.

Alex then explained to him that she came down here to find something she misplaced, Y/n wasn't all that too bothered with what it was because he can't look away from her tits, he's not sure when she got them but they are there now and their making sure to keep his attention, maybe it was because he didn't cum with Haley, he's literally cockeyed but that's one thing she has that her sister hasn't.

Y/n: Were you in here masturbating...?

Y/n asked out of the blue cutting her off from her explanation, she's cute and adorable but she can sometimes over explain shit, which is a little bit of a turn off to Y/n, it's why he loves Haley, she doesn't out smart him, although she is smarter than him, she plays dumb though because she wants to be popular in school, Y/n knows the real Haley and adores her but he can't help but really want her sister right now, especially seeing her blush and nod to the question he asked.

Y/n: ... And you were thinking about me?

Alex looked up to him his cock is still pretty hard, not as hard as it was moments ago but still hard enough to fuck something, she took her mind off that though since she didn't cum either and nodded to him, Y/n felt a little bit of an ego boost when he saw her nodding but he can't do anything about it, he does love Haley and he doesn't want to break her heart, although he got a little curious about something.

Y/n: Can I ask you a personal question?

Alex nodded to him as she stood with her back against the wall, literally and figuratively, there was no way out of this without getting past him and since he's standing in the doorway, she can't really go anywhere, only stand here and answer his questions, so she nodded to him while playing with her fingers nervously.

Y/n: Are you a virgin? Have you ever had sex before? Done anything before?

He didn't need to go into detail, she knew what he was asking and although she hated the fact that she's done nothing with anyone before, she was pretty proud of it, she wanted her first time to be with someone special, someone like Y/n, he's pretty special and she's pretty sure she saw him glance at her chest, maybe he does want her as well, but can she betray Haley like that.

Y/n: Can I ask just one more? Then you can go and we'll pretend this never happened.

That's all Alex wanted to do right now, especially not knowing how long Haley's going to be, Y/n though has changed his tone pretty quickly from not wanting to break Haley's heart to wanting to get his climax, this time using the person that ruined him getting to cum, if it wasn't for Alex moaning his name, he would have already cam inside Haley and they'd both be upstairs right now, but instead he's here talking to his girlfriend's sister with a still pretty hard cock.

Y/n: Do you want me to fuck you?

Alex didn't expect him to ask her that, she just thought it was going to be something casual or something about her thinking about him, instead it was that, she wish he hadn't asked that though because her tongue got tied and he stepped towards her, his hand gently brushing her hair out the side of her face, tucking it behind her ear, it was clear she was a nervous wreck but when both his hands cupped her face and made her look up at him, her panic seemed to leave, until he leant into her and pressed his lips to hers.

Y/n: Was that your first kiss?

Alex nodded to him as he smiled, she looked down to the floor, but instead looked right at his cock to see it twitch, he really wants this and so does she, she's been fantasizing about him for months, she's just really nervous and worried about it, it's normal to be scared on your first time having sex, that doesn't mean she wants him to stop.

Y/n: Tell me. Tell me how much you want me to take your virginity.

Y/n pushed his body against her a little more, she could now feel his cock against her covered pussy and it made her gasp with a small shiver, she really, really wanted this and it made Y/n smile, he's not going to do anything though until she tells him to, Y/n made it worse for her as his lips went to her neck, leaving little kisses there making Alex turn more into putty in his hands.

Alex: I want you to. Please take my first.

Y/n pulled back and looked at her, she has that hungry look in her eyes that Haley get's so many times, so he knew what to do, he pushed his lips back into hers and made out with her a little, she wasn't as good as Haley was and pretty much gave up without a fight, Y/n didn't mind because knowing she's a virgin turned him on and made his even more harder than before, while Y/n is kissing her, he pushed her pants down a little, Alex knew what he wanted and helped him, eventually her pants and panties were on the bathroom floor.

Y/n: Ready?

Alex nodded to him, they didn't have long so that pushed all the foreplay out the window, then again she was too excited to need it and Haley already sucked his cock earlier so he's probably alright with skipping it, what Alex didn't expect was for Y/n to lift her up and pin her to the wall, her legs instinctively wrapped around him as he pushed his cock inside her pussy, it was so much better then her fingers or any toys she's ever used.

Y/n: Take it easy.

Y/n didn't want to hurt her, sure he shouldn't be in this position to begin with but he just needed to and Haley wasn't in the mood anymore, it would have ruined things if he asked her to make him cum, not that screwing her sister instead isn't bad but this is easier to keep a secret from her other then unwanted sex, that's not fun for anyone.

Y/n: This will probably hurt.

Y/n's remembering from his first time with Haley it was over quickly and she experienced a little bit of pain when Y/n would push deeper inside her, Alex already understood all this from the classes and what not, it was a good thing she listened because she was told to breath during this moment and that's what she did, she looked into Y/n's eyes as he gently fucked her, panting deeply.

Y/n: Your so fucking tight. It's incredible.

Y/n looked down to see his cock pretty much half way through this is the part that no matter how many classes you go to it's never going to prepare you for, he pushed all the way inside her, making her cry out in pain, Y/n expected it though and he was able to cover her mouth so her scream was heavily muffled, Alex was breathing heavily into his hand and through her nostrils, Y/n though was trying to do everything he can by staying as still as possibly but he could honestly cum just from how tight she is, Haley was the same though, maybe it's a Dunphy thing, the girls are just really fucking tight.

Y/n: Ready?

Alex nodded to him with watery eyes, he could never understand the pain but he wanted to change that to pleasure, so he started to thrust into her, pulling all the way out till only his tip was inside her then gently pushing his way back in, his hand still covered Alex's mouth because she was still screaming in pain, it wasn't long though till she started to enjoy it, her eyes filled with lust again while she started to bounce matching his movements, Y/n smiled to her then removed his hand, to hear her moans and groans.

Hearing a virgin moaning and loving their first fuck was so hot, but it wasn't going to last long, Alex already felt her climax fast approaching and thanks to Haley's work earlier, Y/n was close to cumming as well, so he needed to find something out first as Alex slowed down her bounces.

Y/n: Are you protected?

Y/n would have cam inside Haley long before now but she's taking the pill, Y/n isn't wearing a condom and is raw dogging his girlfriends sister, he's just had the thought that he might have had some of Haley's pre cum on his cock still but now it's inside Alex, that's the hottest thing he's ever thought and it made his fuck her harder drawing their climax's closer and closer.

Alex: No...

It was all she could get out as Y/n went faster and faster trying to make sure Haley's pre cum is inside her sister, it's sick and twisted but it's what made Y/n cum the quickest, pulling his cock out of Alex, letting her fall back to the floor before moving her to her knees, Alex didn't really know what was happening till Y/n jerked his cock off on her tits and shot his load all over her bust, tapping his cock on her tits to make sure she got all of his cum and honestly it was a pretty big load, Alex panted from her orgasm while looking down at him.

Alex: Wow. That was... That was the best.

Y/n chuckled to her then picked her back up, putting her down on her feet, he gave her one last kiss but then told her she needs to go and get cleaned up, Alex nodded then went to walk away but Y/n slapped her ass making her jolt in surprise, Alex liked it and giggled at him before leaving the bathroom, Y/n followed her out and watched her leave, he can't believe he just cheated on his girlfriend but he's kind of glad he did, Alex was amazing.

Y/n then cleaned up a little before pulling on a clean pair of sweets for tonight, he climbed onto the bed and waited for Haley to come back down and it wasn't long after Alex left a few minutes maybe more, either way, she climbed onto the bed with him and the spark came back for her, Haley started by kissing him then making her way down towards his cock, Y/n couldn't really stop her and tell her she can't suck his did because her sister's virgin cum is still on him, so he just let her do what she wanted to him, it's twisted but it turned Y/n on a little...
